Also known as Loc. 23
Where: Somalia (10.5° N, 50.7° E: paleocoordinates 10.1° N, 49.0° E)
• coordinate based on nearby landmark
• outcrop-level geographic resolution
When: Gargorre Formation (Hafún Group), Middle Miocene (16.0 - 11.6 Ma)
• STRATIGRAPHIC RELATIONS: From the Gargorre Fm [enterers usage] of the Hafún Series [group?], and presumably regionally overlies the Naag Fm [enterers usage] (Early Miocene) and is overlain by the Late Miocene conglomerates. THICKNESS: Difficult to ascertain, but a bed of not great thickness. AGE: Middle Miocene, equivalent to Burdigalian-Helvetian and uppermost Gaj/lower Mekran according to author on the basis of larger formaniferal and molluscan biostratigraphy. STRATIGRAPHIC POSITION: From Bed D, in middle of section.
• bed-level stratigraphic resolution
Environment/lithology: shallow subtidal; lithified, shelly/skeletal, white limestone
Size class: macrofossils
Preservation: cast, mold/impression
